The mold Wheel 2G cznryingM the mold E21 coperates with a iine ofmatrices to cast a slug therefrom. Each line ci matrices 22 is presentedto the mold by an elevator This elevator vcarries a setecrevv 2,4 whichis arrangedto cooperate with a pin 25 on the uppefend of a controllingbar 26. T his controlling,1 bar is normally held yieldably in elevatedposition by a spring 27 and it carries a projection 23 which is arrangedin cooperative relation. with asliding pin 29, the latter being pushed.toward the projection 28 on. the controlling bar by the mold projection30 on the mold Wheel., `When the elevator operates properly to correctlypresent a line oi matrices to the mold, the setscrew 2d on the elevator'will operate tln'ough the pin 25 'to depress the controlling bar 2G andthereby carry the projection .23 into a position to clear the pin 29when the latter is moved forward and, hence, the controlling, har Willremain inoperative. lf, however, the elevator fails to operate to anextent sufcient to correctly presentthe line of matrices to the mold,the set-screw 24 will fail 'to depress the controlling' bar 26sufliciently to cause the projection 23 thereon to clear the pin 29, andwhen the latter is pushed :torward hy the mold wheel will operate uponthe proiection 23 to roch thc controlling bar 226, and t ough the agencyof mechanism to des ced, the clutch Will be automatiin inoperativecondition and the opera on of the machine will be interrupteo...according to the present invention, the controlling bar 26 is arrangedto bear upon one end or a lever 31, this lever 31 being nlcruined on afixed pivot 32 and the opposite end of the lever 31 bears against aroller or projection 33 on one arm of a hellcranlr lever 311, the latterbeing pivoted at 35 Within a housing 36 and it has an arm 37 which Willoperate to lock the hand lever from operation. The roller or projection33 is held in engagement with the lever 31 by a tension spring 33. Thehand lever 39 which enables the operator to start and stop the machineis pivoted on the pin 19 and the unguleriy exte'zding; arm 40 thereof isprofi with a hoohshapod lu or projection oiL the con Y ing handle c isalso operatively conoar i3 by a linlr 4:2. When the operative parts ofthe machine are'in proper relation, the handle 3f) can be op erated toset the clutch in driving' condition to start the machine 'as the springwill hold the locking arm 39 clear of the lockingf lng or projection 41on the handle, the sctting; ot the clutch in driving condition being'effected by a downward movement of the bar. 13, with reterence to Fig.l., a rocking et the bell-crank lever lil, and expansion of the or startnected to 'the t permits the spring 1G which operates to force theclutch shoes 3 into engagement with the clutch face on the main drivingpulley 1n However, should the elevator 23 fail to travel a sulli cientdistance to correctly present a line or" matrices to the incid, thecontrolling bar 26 will not be depressed a distance suilicient to causethe projection 28 thereon to clear the pin 29, and this pin will bepushed forward vby the mold Wheel and Will operate on the projection 28to rock the controlling bar 26. This controlling bar will then bearagainst the adjacent end posits end of this lever will push against the33, thereby causing the roller or projection arm 37 to bear against thelug or pro]ec itt the handle tion 41 on the arm 40 and to sh 39 into aposition to set the clutch in inoperative condition, therebyinterrupting automatically the operation ofthe machine. rlFhis arm 37after setting the clutch in inoperative condition engages beneath thelug or projection 41 and thereby locks the handle 39 lfrom movement in adirection to restart the machine and the machine cannot be restarted bymanipulation of the handle 39 until the elevator has been properlyreset, whereupon the lever 31 will be released by the controlling har26, and the hell-crank lever will return to normal inoperative positionunder the iniiuence of its spring 38, the arm 37 releasing the lug orprojection 41 and then permifttingn the handle '39 to be operated to setthe .machine in operation. The housing 3G which covers' the locking;member 3i and 'the cooperative parts prevents tampering with the lockingmechanism and, hence, it is necessary for the operator to restore themachineto proper condition before attempting to restart it.

The elevator 23 is mounted to slide in a trame i3 commonly known as thevise frame which is pivot-ed at its lower end and is adapted to be swungoutwardly to facilitate rearrangement ot the line of matrices by hand.,as shown and described fully in the patent to Mergenthaler No. 436,531granted September 16, 1890. Upon this vise frame are also mounted thepin 29, the controlling bar 2G, and the lever 31. @pening movement ofthe vise iframe 43 carries the lever 31 out oi' engagement with theroller 33 and spring; 33 to discngage the arm locking projection 4l onthe ln machines as heretofore constructed, the opening` movement of thevise frame would allen7 the clutch spring 10 to act Without interferenceto restart the machine, but according; to the present invention, the armand the link 4-2 form a toggle which, when the clutch is thrown out ofopera-tion, eliiectually` locks the clutch against the action of thespring 10, and the machine cannot be restarted unless the hanle orstarting device 39 is positively pulled 3'? from the starting device.

of the lever 31 and the opforward. `When the clutch is automaticallydisengaged to prevent operation of thc inachine, owing to incorrectpositioning of the 4line of matrices before the mold by the elcvator,the arm 37 of the bell-crank opcrates to positively straighten thetoggle and to lool: it `in such condition so that the ma chine cannot berestarted by jarring of the handle or starting device 39 when the vise"rame is released and swung into open positlon.
